HEINRICH KOPPERS, OF ESSEN-ON-THE-RUHR, GERMANY.

COKE-OVEN.

SPECIFICATION forming part of Letters Patent No. 753,146, dated February23, 1904.

Application filed August 27, 1903. Serial No. 170,926. (No model.)

To aZZ whom it may concern:

Be it known that I, HEINRICH Korrnns, a citizen of the German Empire,residing at Essen-on-the-Ruhr, Germany, have invented certain new anduseful Improvements in Coke- Ovens, of which the following is aspecification.

In the manufacture of coke it has been shown by practice that incoke-kilns with vertical flues the hot gases can be utilized to betteradvantage and at the same time the fireproof material of the kiln beless exposed to destruction by melting if the hot gases and the airintroduced from outside are kept apart, not being permitted to get intouch with each other at a level lower than that of the surface of thecoal undergoing the coking process.

My invention relates to improvements in such kilns with a view ofsecuring the aforementioned advantages. I attain this object by theconstruction described herein and illustrated in the drawings, formingpart of this specification, in which Figure 1 is a plan view of thelower part of the ovens, and Figs. 2 and 3 are vertical sections of mydevice.

As shown, the coke-kiln is provided with vertical fines, under which isa channel for the distribution of the hot gases, the latter passing intothe several fiues through nozzles b, one in the bottom of each flue. A'conduit, serving as or fitted to receive a nozzle (0, passes through theabutment of the structure below from the air-channels under thecoking-chambers into each of the aforesaid fines, preferably under anangle, so that the air is forced into the fines in such a way that itsurrounds the hot gases ascending vertically from the nozzle 5 withoutdisturbing the as cending column of gas and following the same in itsupward motion, inclosing the gas and floating around it in a helical orscrew- The effect obtained thereby is that the process of combustionwill go on in No. 87,641,) I have applied for Letters Pat-- ent on aconstruction and combination similar to the above described, a patenthaving been issued to me September 15, 1903, No. 7 38,918. The maindifference between the invention described in said patent and thepresent invention is in the direction in which the air is admitted intothe gas-lines. According to my former invention, the air enters theflues in a right angle, mixing with the gases at once, while this iscarefully avoided in the present invention.

Vhat I claim as new, and desire to protect by Letters Patent, is

A coke-oven comprising in combination with the usual coking-chambers andthe heating-fines, provided with nozzles at the bottom for the admissionof a vertically-ascending gas-column, inclined channels connecting theair-conduits with the base part of the heatingflues, the inclinationbeing out of line with the ascending gas-column in order to leave itundisturbed, and to circulate aroundit, substantially as described andfor the purpose set forth.

In witness whereof I have hereunto subscribed my name in the presence oftwo witnesses.
